Werner - I know what you mean about the CTE.  They've lumped the CTE above
and below the Tg into one parameter.  I think all material suppliers should
be required to supply CTE from 25C to the material Tg and from the Tg up to
260 or 288C.

 Hi 'Netters,

NELCO4000-13 dat sheet gives no modulus. Also it gives "Z Axis Expansion 
[50°C to 260°C] = 3.5%"--does this mean CTE (z) = 167 ppm/°C? [Sure is a
strange 
way to give a CTE]

Regards,
Werner Engelmaier
